Forest land is a broad land use class defined in the Swedish Forestry Act. The definition the same as the UN's Food and Agriculture Organization (FAO) definition of Forest Land and is internationally accepted. Forest land is defined as land with trees hiher than 5 meter and a canopy cover of more than 10 percent, or trees able to reach these thresholds in situ.
Of the total growing stock of 3531 miljoner m³sk approximately 40% is pine and 40% spruce. Today there is ca 27.9 million hectare of Forest land. All data presented are including areas within national parks and nature reserves.
Age distribution within Sweden's forests show that the most common age group is 41-60 years. Many species are connected to old forest and the there are circa 3.5 million hectares of forest older than 140 years which represents ca 12.7 percent of the forest land area. This type of forest is most common in Norrland where is a a significant proportion of the forest land area (ca 18% i northern Norrland and ca 15% in southern Norrland). In southern Sweden there is little forest land with an age over 140 years.
The volume of dead wood in forest land areas is an established measure of the level of biological diversity. Many species are dependant on dead wood in different stages of decay and the lack of dead wood is one of the primary threats to many endangerd species in the forest landscape. Seen for the whole country the volume of dead wood is 266 million m³ or 9.5 m³ per hectare. Roughly half of this dead wood is classified as hard dead wood and the rest in different stages of decomposition.
The total tree dry biomass, a key value in climate issues, is 2644 million tonnes dry weight for forest land in Sweden.

About official statistics
SLU has been appointed by the Swedish government as responsible for the official statistics about the state and change of Swedens forests. Read more about SLU's official statistics. The Swedish Forest Agency is the responsible authority for felling statistics produced by SLU. As an authority responsible for official statistics SLU must make sure that:
- All statistics are objective
- All statistics are well documented
- All statistics are quaility assured
Official statistics must be made available without cost and also be accessable in electronic form.
All official statistics must be clearly marked maked with Offiicial Statistics of Sweden or bear the following logotype:
